Squamous cell carcinoma and pilonidal cyst disease.
Annali Italiani Di Chirurgia
|February 20, 2015
Summary
Squamous cell carcinoma can rarely develop on chronic pilonidal sinus disease. Early detection through inspection and biopsy is crucial for managing this rare complication.
Area of Science:
- Dermatology
- Oncology
- Surgical Pathology
Background:
- Pilonidal sinus disease (PSD) is a common chronic inflammatory condition.
- Complications include cellulitis, abscess, and recurrence.
- Malignant transformation to squamous cell carcinoma is a rare but serious event.
Observation:
- A case report details a 63-year-old male with a 43-year history of recurrent PSD.
- The patient developed squamous cell carcinoma on a chronic pilonidal cyst.
- Diagnostic procedures included incisional biopsy and total body CT staging.
Findings:
- Radical surgery was performed for the malignancy.
- The patient showed no evidence of recurrence 30 months post-surgery.
- Malignant transformation in PSD is reported at 0.02%–0.1% incidence.
Implications:
- Chronic and longstanding inflammatory lesions in the pilonidal area warrant thorough inspection.
- Incisional biopsies are recommended to rule out malignant degeneration in persistent PSD.
- Prompt diagnosis and treatment are vital for managing rare complications of PSD.

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Skin Diseases and Disorders

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Accessory Structures of the Skin: Sebaceous Glands
5.8K
A sebaceous gland is a type of oil gland found almost all over the skin ( except palms and soles) and helps lubricate and waterproof the skin and hair. Most sebaceous glands are associated with hair follicles. They generate and excrete sebum, a mixture of lipids, onto the skin surface, thereby naturally lubricating the dry and dead layer of keratinized cells of the stratum corneum, keeping it pliable.
These glands that produce the oils on the skin and hair are holocrine glands. The mature...

Acne Infection
72
Acne is a multifactorial skin condition primarily affecting adolescents and young adults, with a global prevalence estimated to exceed 75% in this demographic. The condition is characterized by the formation of comedones (blackheads and whiteheads), papules, pustules, nodules, and, in severe cases, cysts, particularly in areas rich in sebaceous glands such as the face, neck, chest, and back. The pathogenesis involves increased sebum production, follicular hyperkeratinization, colonization by...

Abnormal Proliferation
5.5K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Assessment of the Rectum and Anus
2.0K
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.
